INTERPRETATION OF THE STONE

If you enjoy kitchen knife sharpening and Japanese woodworking tools like Kanna, this stone is the perfect combination for both. Medium hard but produces mud quickly, very fine with strong cutting speed, giving an incredible edge.

The stone has good overall feedback but can be a bit grabby depending on your stroke orientation but with lighter pressure posed no issues. Being a very fine stone with good slurry, I was able to pull out some unique detail in standard Tanaka sanmai cladding and wrought iron cladding. Using a little water to start a mud on the stone with pressure on the soft iron could produce a dark blackish grey swarf.

Tested both on single bevel and double bevel kitchen knives as well as Kanna the stone handled both easily and excelled in edge sharpening. If one’s pressure is light and controlled this stone was great in Honyaki single bevel with a fine toothy edge. Recommended for those with natural stone sharpening experience.

RECOMMENDED USE FOR :

Best suited for kitchen knives and Japanese wood working tools especially Kanna, Single and double bevel iron clad carbon steel.

Prepared for Use

Komon does more than simply select workable natural stones.
Even the finest natural stone cannot be used for sharpening straight from the mountain. Each stone must be carefully prepared and finished before it is ready for use.

At Komon, each stone is carefully prepared and finished by craftsmen with extensive experience and knowledge of natural stones, so that its qualities can be experienced from the moment it is put to use.

  • A STABLE BASE

    We carefully flatten the back side to ensure stability during sharpening. When additional support is needed, we attach a wooden base to create a secure foundation.

    Any wobbling of the stone affects the precision of the sharpening process; stability is particularly crucial during final polishing and edge sharpening.

  • A READY-TO-SHARPEN SURFACE

    The sharpening surface is flattened and prepared for use.
    Softer stones intended for polishing and finishing are given generously rounded edges. Harder stones used for edge sharpening are also carefully rounded to prevent the stone from damaging the blade.

    As a natural stone is used, new layers of stone will gradually appear. Regular flattening and maintenance are therefore essential to keep the stone performing at its best.

  • PROTECTING THE STONE FOR YEARS TO COME

    Natural stones are formed by nature, and some may contain weaknesses that could eventually develop into cracks.
    We identify these stones in advance and, when necessary, reinforce the surrounding areas with cashew resin to help prevent future damage.

    Cashew resin can scratch a blade. Before use, any exposed cashew resin on the corner should be carefully rounded with a medium grit diamond plate.
